Nuraghe San Pietro, Bronze Age nuraghe in Torpè, Italy.

Nuraghe San Pietro is a complex nuraghe built of roughly hewn red trachyte and schist blocks on a low rise by the Rio Posada. It has a central keep with four side towers, a walled courtyard with a 5.8 m deep well, and a narrow entrance corridor. The keep's chamber has three cross-shaped niches and a collapsed tholos roof.

The nuraghe was probably built in several phases, with the central tower and four side towers of roughly hewn red trachyte and schist. It belongs to the Nuraghe culture (about 1600–400 BC), linked to the earlier Bonnanaro culture (2200–1600 BC). Among the most notable finds is a Late Bronze Age clay figurine.

The name San Pietro corresponds to Saint Peter, and in Sardinian the site is called Nuraghe Santu Predu. The nuraghe was probably built in several phases, and among the most notable finds is a Late Bronze Age clay figurine.

The nuraghe stands on a small rise in the alluvial plain by the left bank of the Rio Posada. Access to the central tower is through a narrow corridor 2.8 m long and 0.8 m wide, ending under a lintel about 1 m high, so visitors must bend down. The courtyard is the only way into the mastio.

The northeast tower preserves a low stone bench along much of its base, about 0.3 m high, and a clay layer at its centre marks a hearth. A 6.8 m blind corridor opens off its south wall, probably used for storage.
